Fix compiler warning

The local variable off is uninitialized on 'goto fill'.
Initializing with 0 seems to be appropriate to fix following gcc warning
although off is actually always initialized as the function returns with
1 on 'if (!i)' case.

options.c:920: warning: 'off' may be used uninitialized in this function
